23a211cbba lavc: change all decoders to behave consistently with AV_EF_CRCCHECK.
Just crccheck prints a warning, crccheck+explode returns an error.

Also document this behavior.

5778299c7e ttadec: fix last frame handling when seeking
Using a frame count, as is done currently, does not work at all with
seeking. Instead, when the number of samples in the final frame has
been decoded, we check if only the 32-bit CRC is remaining. If so, we
assume that it is the final frame.

There is no longer a need to keep total_frames in TTAContext.

ac80b812cd tta: prevents overflows for 32bit integers in header.
This prevents sample_rate/data_length from going negative, which
caused various crashes and undefined behaviour further down.

aaf47bcde7 Drop ALT_ prefix from BITSTREAM_READER_LE name.
The prefix is a historic remnant that probably meant "alternative".
Now that the A32 bitstream reader has been dropped it makes no sense anymore.
